I'll read it once I finish Hanako's route. I have no doubt Hisao's presence has a meaning, and a big one at that.
But Hisao is also present, although in a different way, in Lilly's route, and because Hanako tries actively on her own to give Hisao and Lilly some space, that fact itself may also work as some sort of a force pushing her towards opening up to others.
Hisao's presence is vital in both ways, but it seems to work slower and in a different way in Hanako's route. HOWEVER, I am saying that from the perspective of a person who hasn't finished Hanako's route yet.
Faster finish Hanako's path!
I think Hanako does fall in love with Hisao, even in Lilly's path.
In Lilly's path, at one of the tea party sceen, Hanako mentioned she doesn't mind if being seen by Hisao in her pajamas. (nosebleed).
She doesn't feels the need to change when she is with Lilly.
But when Hisao come into the picture,
she feels that 'even Hisao is treating me the same as Lilly'
that is why she gets weird ideas. (DO NOT see if you have not finish Hanako's path ->weird ideas about being broken person, and needs protection.
Hence, deciding to buck up and slowly change herself.
PS: The timeline of KS in Lilly paths, is set in slightly more towards the future, compared to the timeline in Hanako path.
Hence more time for Hanako to grow.
I'd like to finish quicker, but alas, I can't. Both my own emotional investment into Lilly's route and my studies drastically slow down my progress in KS paths, even those I'd like to complete.
It's possible that Hanako feels someway differently about Hisao even in Lilly's path, but those emotions are nowhere nearly as strong as in her own and may simply come from the fact that Hisao is probably the first guys since she hit puberty that treats her right. Similarly, Hisao shows strong signs of finding Lilly attractive in Hanako's path, but since he just doesn't feel about her the way he seems to think he feels about Hanako, he does not pursue her.
I've seen the class breakdown scene yesterday and I have to say, it is quite disturbing especially since I can somewhat identify with Hanako at that point. I had two moments of utter breakdown at school in my life and I handled neither well. One was my overt anger bursting on everyone (only time I ever initiated not one, but three school fights on my own). Other was soon after, but this time, I simply turned of similarly to the way Hanako did.
But not to that extent. "Cold Iron" playing didn't help either. It seems her mental scars and still fresh wounds lie deep and it's good Mutou reacted so well.
Poor Hanako, I'm surprised Mischa didn't try to give her a hug
Progress : Lilly - finished (Good ending), Hanako - finished (good ending), Rin - finished (Good ending), Shizune - finished (Bad ending), Emi - Finished (good ending)
Lilly=Rin > Hanako > Emi=Misha > Shizune
